>// 合并table单元格
objectSpanMethod({ row, column, rowIndex, columnIndex }) {if (columnIndex === 1) {  //定位到维度列// 获取当前单元格的值const currentValue = row[column.property];// 获取上一行相同列的值const preRow = this.tableData[rowIndex - 1];const preValue = preRow ? preRow[column.property] : null;// 如果当前值和上一行的值相同，则将当前单元格隐藏if (currentValue === preValue) {return { rowspan: 0, colspan: 0 };} else {// 否则计算当前单元格应该跨越多少行let rowspan = 1;for (let i = rowIndex + 1; i < this.tableData.length; i++) {const nextRow = this.tableData[i];const nextValue = nextRow[column.property];if (nextValue === currentValue) {rowspan++;} else {break;}}return { rowspan, colspan: 1 };}}
},
